Abstract

Three new bisabolocurcumin ethers, named demethoxybisabolocurcumin ether (1), bisabolocurcumin ether (2), and didemethoxybisabolocurcumin ether (3), along with two known compounds, 4 and 5, were isolated from the AcOEt extract of the rhizomes of Curcuma longa L. Their structures were established by the analysis of NMR and MS data. The new compounds 1–3, which possess a new 1,7‐diarylheptanoid skeleton linked with a bisabolone‐type sesquiterpene substructure by a CO bond, were found for the first time in a natural source.
